Customer Success Manager

Mercura (YC W25) helps the companies that build the real world move at software speed, automating the back-office work that runs the $12 trillion industry behind every hospital, school, and power plant. We started with one of their biggest bottlenecks - turning messy technical requests into accurate quotes - and grew to $2M ARR in our first year. With a team of 16, we're now targeting $10M by the end of 2026 as well as our expansion into the US.

About the role

As our first Customer Success Manager, you will own the customer journey end-to-end — ensuring every user gets maximum value from Mercura. You’ll be involved throughout the full lifecycle: from expert discussions during sales, onboarding users, holding workshops, to expanding existing relationships.

Working closely with our CPO, sales, and engineering teams, you’ll translate customer feedback into actionable insights, influence the product roadmap, and drive product adoption. You’ll build strong, lasting relationships, proactively engage customers, and develop tailored success strategies that ensure satisfaction and measurable impact. As a trusted advisor, you help customers achieve their goals while advancing Mercura’s growth ambitions.

What you will be working on

• Customer relationships: Act as the main point of contact and trusted partner for our customers, driving satisfaction and long-term partnerships.

• Lead onboarding and implementation: Guide customers through onboarding and implementation - ensuring quick time-to-value and long-term engagement.

• Develop deep product and customer expertise: Develop a deep understanding of our software and customers, and champion customer needs in the product roadmap.

• Value creation: Help customers unlock measurable savings and efficiency gains, and support them during key negotiations.

• Own account success: Drive Mercura’s adoption through training and best practices, while managing accounts for retention, growth, and long-term strategic partnerships.

• Cross-functional collaboration: Work closely with our CPO, sales and engineering teams to ensure customer feedback shapes product development.

What we’re looking for

• You have 1+ years of experience in customer success, account management, or managing client relationships in SaaS, B2B, or consulting,

• You are a strong communicator, with the ability to engage confidently with C-level stakeholders and build trusted relationships.

• You are a proactive, empathetic and people-oriented team player, committed to supporting others and creating lasting satisfaction and business value.

• You have strong problem-solving skills and an analytical mindset that allows you to understand and present complex issues clearly.

• You are pragmatic, solution-oriented, and motivated to build something and grow with us

• Ideally, you have initial experience with construction, supply chain, and the trades

• You are willing to work five days a week from our Munich office with a higher intensity than in a 9-5 job, with occasional customer travel

• You are native in German and fluent in English

Company Perks

• Free team dinner (up to 4x/week)

• An ambitious and caring team that sees their work as more than just a job

• UrbanSportsClub membership - join our team workouts 3x/week

• Easy relocation to Munich — our office is located in the Werk1 Startup Incubator, where you can rent a 1-bedroom apartment right next to the office for just €800/month

• Access to any AI or productivity tools you need

Why Mercura

• Join an ambitious and caring team: Your future colleagues are experienced operators, ex-founders, Science Olympiad medallists, and top graduates from places such as Google, Bain, MIT, TUM, Harvard, CDTM, and Cambridge. We bring extraordinary people together and deeply invest in your growth as your mentors, teammates and friends. We care, trust, and support one another, and we make sure that fun is at the heart of everything we do.

• Work with the latest tech: AI is at the core of our product, and use the latest tech across our product and processes to tackle meaningful challenges and shape how users interact with AI.

• Thrive in a high-growth, high-commitment environment: We’re growing extremely fast because we always put our work and our customers first. If you excel in fast-paced settings and want to grow as part of something big from day one, Mercura is for you.

• Build something with real-world impact: We ship code that directly helps a massive, yet overlooked manual industry run more efficiently and sustainably. With us, you can work on AI that contributes to economic growth and stability on a huge scale.

• Build a company: As an early team member, you will have a direct, lasting impact on our culture, processes, technology, and product. Joining us offers immense rewards: ownership, financial upside, and hands-on experience building a company from the ground up. Our track record speaks for itself - over five Mercura alumni have gone on to found their own companies and raise millions after their time with us.

Enjoy the ride. We build a culture where people can be themselves, have fun doing meaningful work, and celebrate wins along the way.
